Abstract
In some aspects, the techniques described herein relate to a gate valve configured to engage an outer surface of a wall of a reaction chamber to form a seal about an opening in the wall of the reaction chamber, including a plate including a groove; a seal element disposed within the groove; and a hinge mechanism coupled to the plate and to the reaction chamber, the hinge mechanism being configured to translate between a closed position in which the plate and the seal element are pressed gain the wall of the reaction chamber in a direction that is perpendicular to the outer surface of the wall and an open position in which the plate and the seal element are not in direct contact with the reaction chamber.
Claims20
A gate valve configured to engage an outer surface of a flange of a wall of a reaction chamber to form a seal about an opening in the wall of the reaction chamber, the gate valve comprising:
- a plate including a groove;
- a seal element disposed within the groove;
- and
- a hinge mechanism coupled to the plate and to the reaction chamber, the hinge mechanism being configured to translate between a closed position in which the plate and the seal element are pressed against the wall of the reaction chamber in a direction that is perpendicular to the outer surface of the wall and an open position in which the plate and the seal element are not in direct contact with the reaction chamber.
A gate valve configured to engage an outer surface of a flange of a wall of a reaction chamber to form a seal about an opening in the wall of the reaction chamber, the gate valve comprising:
- a plate including a groove;
- a seal element disposed within the groove;
- a bracket removably coupled to the plate;
- a frame;
- a first hinge rod connected between the frame and the bracket;
- a second hinge rod connected between the frame and the bracket, wherein a length of the first hinge rod is less than a length of the second hinge rod;
- and
- a hinge mechanism including an unequal four-bar linkage that includes the frame, the first hinge rod, the second hinge rod, and the bracket, wherein the frame is configured to couple to the reaction chamber, the hinge mechanism being configured to translate between a closed position in which the plate and the seal element are pressed against the wall of the reaction chamber in a direction that is perpendicular to the outer surface of the wall and an open position in which the plate and the seal element are not in direct contact with the reaction chamber.
A gate valve, comprising:
- a plate including a groove;
- a seal element disposed within the groove;
- a bracket removably coupled to the plate;
- a frame;
- a first hinge rod connected between the frame and the bracket;
- a second hinge rod connected between the frame and the bracket, wherein a length of the first hinge rod is less than a length of the second hinge rod;
- and
- a hinge mechanism including an unequal four-bar linkage that includes the frame, the first hinge rod, the second hinge rod, and the bracket, wherein, when the frame is coupled to a flange of a reaction chamber, the hinge mechanism is configured to translate between a closed position in which the plate and the seal element are pressed against the flange of the reaction chamber in a direction that is perpendicular to an outer surface of the flange and an open position in which the plate and the seal element are not in direct contact with the reaction chamber.
